DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication terminal network control device used in a data communication system using no ringing communication.

[0002]

2. Description of the Related Art The main application of a data communication system using no ringing communication is telemeter communication. The telemetering by the no ringing communication is shown in FIG.
As shown in FIG. 7, a telemeter communication terminal network control device 30 connected to a telemeter terminal device such as a gas meter 35 and a water meter 36 is connected to a home telephone 34 which is a telephone terminal device via a no-ringing communication line 33. A telemeter communication system is configured by connecting to the device 31. Telemeter communication terminal network controller 30
Stores basic operating conditions, destination telephone numbers, and the like in a storage device, operates by a no-ringing incoming call from the center device 31, and communicates with the center device 31 to transmit data of the telemeter terminal. Meter reading can be performed by a gas meter or the like, and data of the telemeter terminal device can be transmitted to a predetermined destination at a set time.

[0003]

The telemetering by the above-mentioned no ringing communication uses a half-duplex communication system at a transmission speed of 1200 bits / second or less. There is such an upper limit of the communication speed because, in the current system of the no-ringing service, the no-ringing control signal (2765 Hz) for controlling the no-ringing trunk 32 is always superimposed on the link as shown in FIG. If the communication speed is higher than the above, the no-ringing control signal becomes noise, and high-speed communication at 1200 bits / sec or more becomes difficult. No-ringing communication is effective when applied to low-speed data communication such as meter reading of gas meters as described above. However, in systems that transmit and receive large amounts of data and systems that require real-time performance,
There is a problem that no ringing communication is difficult to apply. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a data communication terminal network control device capable of performing high-speed data communication without being limited by the communication speed of the no-ringing communication while taking advantage of the no-ringing communication. The purpose is to provide.
